ABSTRACT

The present device concerns an ultrasonic aroma humidifier which facilitates cleaning. For this purpose, the present device comprises a main body, a vaporizer which is coupled with the bottom of the main body, and a base. The main body includes a water shortage indicating lamp, and a handle with a built-in air blowing port, wherein a water container and a water container mount are formed. The vaporizer includes: an ultrasonic oscillator which generates sprayed mist through an ultrasonic oscillation, a water level detecting sensor which detects the water level, a circuit board for controlling the ultrasonic oscillator when there is a lack of water and turning on and off the water shortage indicating lamp, and an electric connector which supplies electric power to the ultrasonic oscillator. The base houses an electric connection protrusion which is coupled with the electric connector, ultrasonic oscillation and control circuits which respectively drive and control the vaporizer, a blowing fan for taking in external air, a humidifying switch which regulates the degree of humidification, a blowing switch which regulates blowing intensity, and a power source cord. The top of the main body is coupled with a cover in which a humidifying outlet for discharging humidifying particles and a nozzle are included. In the inner side of the main body, an attachable/detachable filter net storing aroma and cosmetic materials and a stationary ring are included. According to the constitution as the above mentioned ultrasonic humidifier, since the main body has a function as a water tank and a humidifying body, and the air blowing port is handle-shaped, the internal structure is simple. Cleaning and water supply are easy and free because the main body is independently separated from the base wherein an electric circuit and a blowing fan are embedded, using an electric power transmitting method at a contact point. In addition, position change and installation are free and humidification and aroma and cosmetic material discharge are simultaneously enabled by letting a user freely add aroma and cosmetic materials because the filter net for aroma is formed inside the main body.

TECHNICAL FIELD

The present invention relates to an ultrasonic aroma humidifier capable of facilitating cleaning.

BACKGROUND ART

Humidifiers are devices that spray water into the air to maintain humidity that is pleasant and good for human bodies and used to remove respiratory illness and atopic disease etc. due to dry air in an interior or in winter. The humidifiers used for this purpose are largely divided into a heating type, an ultrasonic type, and a composite type.

The present invention relates to the ultrasonic humidifier and an ultrasonic humidifier of the related art is described hereafter.

FIG. 1 is a view showing the top of a humidifying chamber of an ultrasonic humidifier of the related art and FIG. 2 is a cross-sectional view of the ultrasonic humidifier of the related art. As shown in the figures, a water tank seat 21 where a water tank 10 is seated, an ultrasonic oscillator 25 humidifying the interior air by spraying, an air blowing port 26 discharging the sprayed water, and a water level detecting sensor 27 detecting the amount of water for spraying are formed on the top of a humidifier main body 20. The water tank seat 21 has a protrusion 22, such that when the water tank 10 is seated on the humidifier main body 20, a spring type of water supply port 12 in a cover 11 of the water tank is opened and a predetermined amount of water flows into a humidifying chamber 24 through a connection pipe 23. The water level sensor 27 stops the humidification when the water flowing in the humidifying chamber 24 reduces under a predetermined level. In the ultrasonic oscillator 25 and the blowing fan 28 of the configuration, the degree of humidification and the blowing intensity are controlled by an electronic circuit (not shown) that receives operational intensity of the humidifier by a user operating keys of a key input unit 31, such that the water is discharged for humidification into the interior through a spray nozzle 30 at the top of a spray pipe 29.

When the humidifier of the related art is used for a long period of time, the water tank 10 and the main body 20 are seriously contained by propagation of mold or bacteria, such that the humidifier for health rather becomes a cause of contaminating the interior air. In order to prevent this contamination, it is required to frequently clean the water tank 10 and the main body 20. In this configuration, the water tank 10 is separable and can be cleaned, but it is required to separate an individual cover 11 coupled to the water tank 10, such that it is complicated to clean and supply water while the water level sensor 27, the air blowing port, the water seat 21, a cable 32, and the ultrasonic oscillator 25 are integrally formed in the main body 20, such that the structure is very complicated and cleaning is not easy. Further, since the electronic circuit is provided in the main body 20, the water may flow into the air blowing port 26 and the main body 20 in cleaning and damage the insulation of the electronic circuit, such that the humidifier is likely to break and the user is likely to receive an electric shock.

Meanwhile, a humidifier implemented by providing the common humidifier described above with an aroma function is described hereafter.

FIG. 3 shows an aroma humidifier that has been publicized by Korean Utility Publication No. 91-1087. According to the configuration of the aroma humidifier, an air blowing fan 40 is disposed at a side of a case 42 with an aromatic sponge, such that air blown by the air blowing fan 40 flows through the case 42 and aroma is discharged outside through a nozzle 41.

However, the aroma humidifier is not largely different in the structure from the humidifier described above, such that cleaning is not easy. Further, an aromatic is disposed and used in the main body of the humidifier, such that a user cannot freely select and install an aromatic.
